抄録
To observe earth potential difference (EPD) signals induced by seismic waves a modified measuring method has been operated continuously at Aobayama in Sendai. This method is successfuly used to reduce the unnecessary signals induced by artificial and natural earth current sources. We have also obtained seismic waveform records from Earthquake Observatory of Tohoku University which is located apart 700m from us. The earth potential difference signals and three signals of seismic wave (accelaration, velocity and displacement) of the Kobe earthquake are displayed. To analyze these complicated signals the spectrum transform have been performed and compared each others. A streaming potential model associated with earth accelaration is adopted to explain the induced earth potential difference signal. We estimate the ratio of the earth electric field (potential difference) to the pressure difference inside the ground. This ratio is reasonable on the assumpution of the streaming potential model.
